ObjectiveTo investigate the characteristics of injury deaths and its disease burden in Taizhou City from 2009 to 2022, and to provide a basis for the prevention and control of injury. MethodsBased on the injury death surveillance data of Taizhou City from 2009 to 2022, the age-specific and sex-specific mortality rates, as well as the standardized mortality rates after adjusting China’s standardized population age of residents in Taizhou City were calculated. The crude mortality rate, standardized mortality rate, average years of life lost(AYLL), potential years of life lost (PYLL) and potential years of life lost rate (PYLLR) were calculated using Excel 2013 software. Joinpoint 4.2 software was used to estimate the annual percentage change (APC) and analyze the trends of injury mortality and PYLLR from 2009 to 2022. ResultsFrom 2009 to 2022, the standardized mortality rate of injuries in Taizhou City showed a decreasing trend (APC=-4.876%, P<0.001), with a mortality rate of 64.38/100 000 and a standardized mortality rate of 66.68/100 000. There was a statistically significant difference in injury deaths by genders (χ²=7 520.153, P<0.001). From 2009 to 2022, the PYLL and AYLL caused by injuries in Taizhou City were 587 518 person years and 21.91 years, respectively, with a PYLLR of 7.72%. The PYLLR of injuries showed a decreasing trend (APC=-7.454%, P<0.001), in addition, the PYLLR in urban(APC=-7.123%), rural areas (APC=-10.193%), males (APC=-7.595%) and females (APC=-7.046%) all showed a decreasing trend, all differences were statistically significant(all P<0.001). The top five causes of injury deaths leading to PYLL were traffic accident, drowning, accidental fall, suicide and accidental poisoning. ConclusionIn the last decade, injury has been a major cause leading to premature death among residents in Taizhou, with a higher mortality rate in males than that in females, and different injury characteristics caused by different types of injuries. It is necessary to take targeted injury prevention and intervention measures for different key population groups to effectively reduce the disease burden caused by injury deaths.

Objective:To determine the prevalence and associates of hyperuricemia (HUA) among the middle- and older-aged population of the island and mountainous areas in Taizhou City of Zhejiang Province.Methods:A cross-sectional study was conducted on individuals aged 45 and above in the island and mountainous area of Taizhou City. The study included questionnaires, physical examinations, and laboratory tests. Data were primarily collected on sociodemographic characteristics, chronic disease history, lifestyle factors, waist circumference, blood pressure, and serum uric acid levels. The association between hyperuricemia and these factors was analyzed by logistic regression.Results:A total of 971 individuals were included in the study, comprising 468 from island and 503 from mountainous area. The prevalence of hyperuricemia was 17.9%, with a significantly higher prevalence in the island area (25.6%) compared to the mountainous area (10.7%). Stratified by gender and age, differences in the prevalence of hyperuricemia between island and mountainous areas were observed in males aged 55 to 64, females aged 45 to 54, 55 to 64, 75 and above (all P<0.05). Multiple logistic regression analysis showed that high intake of sea food (>3 times/week) was positively associated with hyperuricemia ( OR=2.10, 95% CI:1.33-3.34). Furthermore, separate regionally stratified logistic regression analyses showed that in the island area, male gender ( OR=3.15, 95% CI:1.78-5.66), central obesity ( OR=2.38, 95% CI:1.46-3.93), and hypertriglyceridemia ( OR=2.00, 95% CI:1.22-3.30) were positively correlated with hyperuricemia (all P<0.05). In the mountainous area, the age group of 65 and above ( OR=3.50, 95% CI:1.09-12.50), male ( OR=6.79, 95% CI:2.87-17.81), those employed in enterprises and institutions ( OR=6.57, 95% CI:1.92-23.73) and hypertension ( OR=3.68, 95% CI:1.66-8.87) were positively correlated with hyperuricemia (all P<0.05). Conclusions:The prevalence of hyperuricemia among the middle- and older-aged population in the island of Taizhou City is significantly higher than that in the mountainous areas. Targeted comprehensive behavioral interventions such as routine screening of chronic diseases, low-fat diet, alcohol control, reduced seafood intake, enhanced exercise, weight management, and blood pressure control are warranted.

Objective:To analyze the incidence and risk factors of malignant tumors among HIV-infected patients in Taizhou, Zhejiang Province.Methods:The data were collected from the China Information System for Disease Control and Prevention and the Taizhou Chronic Disease Information Management System. A retrospective cohort study design was used. The subjects were HIV-infected patients who had their household registration in Taizhou from 2005 to 2023 and participated in the follow-up. The observation period was until December 31, 2024. The standardized incidence ratios (SIR) of malignant tumors among HIV-infected patients were analyzed. Cox proportional hazards regression model was used to analyze the influencing factors of malignant tumor incidence.Results:A total of 3 593 HIV-infected patients were included, of whom 292 had malignant tumors. The proportions of AIDS-defining malignancies and non-AIDS-defining malignancies were 12.33% (36/292) and 87.67% (256/292), respectively. The proportion of malignant tumors before and after AIDS confirmation was 43.49% (127/292) and 56.51% (165/292), respectively. 3 466 HIV-infected patients were included in the follow-up cohort, with a total follow-up of 24 968.59 person-years. The incidence rate of malignant tumors in patients with HIV infection was 658.46 per 100 000 (SIR=1.89, 95% CI: 1.61-2.20). The SIR of malignant tumors showed an upward trend with the increase of time. The results of Cox proportional hazards regression model analysis showed that HIV-infected patients in the age groups of 45-59 and ≥60 years (a HR=2.58, 95% CI: 1.26-5.28; a HR=5.00, 95% CI: 2.38-10.51) were more likely to develop malignant tumors. HIV-infected patients with an educational level of senior high school or above (a HR=0.52, 95% CI: 0.29-0.95) and those in the first CD4 +T lymphocyte/CD8 +T lymphocyte count ratio ≥0.5 (a HR=0.52, 95% CI: 0.28-0.97) were less likely to develop malignant tumors. Conclusions:From 2005 to 2023, the incidence of malignant tumors among HIV-infected people in Taizhou was higher than that of the general population, and most of them were non-AIDS-defining malignancies. It is necessary to strengthen the early screening and diagnosis of malignant tumors among HIV-infected patients.

ObjectiveTo analyze the mortality rate and the changing trends of injury in Taizhou City from 2009 to 2022, so as to provide a reference for developing injury intervention strategies. MethodsSurveillance data on injury deaths of the registered residents in Taizhou from 2009 to 2022 were used, and descriptive statistics and χ² test were employed to analyze the mortality rates and differences by age group, gender, and region. Joinpoint regression analysis was used to analyze the trends and calculate the annual percentage change(APC). ResultsFrom 2009 to 2022, a total of 53 707 injury deaths were recorded in Taizhou, with a mortality rate of 64.38/10⁵ and a standardized mortality rate of 66.68/10⁵. The injury mortality rate showed a decreasing trend (APC=-1.30%, P<0.05). The top five causes of death were accidental falls, traffic accidents, drowning, suicide, and accidental poisoning, all showing a decreasing trend (APC=-3.30%, -7.65%, -2.77%, -5.78%, and -7.82%, respectively, all P <0.05). The leading causes of death for those under 15 years old, 15‒64 years old, and 65 years old and above were drowning, traffic accidents, and accidental falls, respectively. There was no statistical difference in the mortality rate between urban and rural areas (χ²=3.81, P=0.05), but there was a statistical difference between genders (χ²=7 520.15, P<0.01). ConclusionIn recent years, injury deaths among the residents in Taizhou have been decreasing. Efforts should be made to strengthen the prevention and control of injuries such as drowning in children, traffic accidents in middle-aged and young people, and accidental falls in the elderly.

Objective:To compare the prevalence of frailty and related factors in middle-aged and elderly people aged ≥45 years in island and mountainous areas of Taizhou, Zhejiang Province.Methods:Based on cross-sectional design, stratified cluster sampling and quota sampling methods were adopted. One administrative district was randomly selected from each of six coastal and three inland administrative districts in Taizhou during July to August, representing two different geographical terrains. In the island area (Jiaojiang District), all residents aged ≥45 years were included by cluster sampling. In the mountainous area (Xianju County), participants were selected through quota sampling, with same gender and age distributions. Data about their demographic characteristics, lifestyle and health-related factors were collected through questionnaire surveys and laboratory examinations. The prevalence of frailty was assessed using the Fried frailty phenotype scale. Hierarchical analysis and multivariate logistic regression analysis were used to compare the influencing factors of frailty.Results:A total of 1 011 local residents were studied, in whom island and mountainous residents accounted for 48.1% (486/1 011) and 51.9% (525/1 011) respectively; men and women accounted for 45.9% (464/1 011) and 54.1% (547/1 011) respectively. Middle-aged (45-49 years), younger elderly (60-74 years), and older elderly (≥75 years) residents accounted for 38.6% (390/1 011), 44.6% (451/1 011), and 16.8% (170/1 011) respectively. The overall prevalence rate of frailty was 3.6% (36/1 011), the prevalence rate was 3.7% (17/464) in men and 3.5% (19/547) in women. The prevalence rates in age groups 45-59,60-74 years and ≥75 years were 0.3% (1/390), 2.2% (10/451), and 14.7% (25/170), respectively. The prevalence rates of frailty and pre-frailty in island area were 6.0% (29/486) and 39.1% (190/486), respectively, which was higher than those in mountainous area (1.3%, 7/525) and (30.9%, 162/525). After adjusting for potential confounding factors, the risk for frailty in island residents was significantly higher than that in mountainous residents (a OR=1.55,95% CI: 1.07-2.25, P=0.019). In island area, older age (60-74 years:a OR=2.52,95% CI: 1.56-4.13; ≥75 years:a OR=11.65,95% CI:5.38-26.70), being women (a OR=1.94,95% CI: 1.20-3.17), suffering from depression (a OR=1.09,95% CI:1.02-1.17) were associated with frailty symptoms. In mountainous area, older age was also associated with an increased risk of frailty symptoms, but the OR value was lower than those in island area (60-74 years: a OR=1.74,95% CI:1.04-2.94;≥75 years: a OR=4.78,95% CI:2.45-9.50). Polydrug use (a OR=2.08,95% CI: 1.14-3.80) and suffering from depression (a OR=1.10,95% CI: 1.02-1.18) had significant positive association with frailty symptoms. Higher education level had significant negative association with frailty symptoms (junior high school: a OR=0.40,95% CI: 0.21-0.75; senior high school and technical secondary school: a OR=0.29,95% CI: 0.15-0.53; college or above:a OR=0.22,95% CI: 0.11-0.42). Conclusions:The prevalence of frailty in middle-aged and elderly community residents was significantly higher in island area than in mountainous area in Taizhou. The frailty-related factors varied with area. The elderly people (≥75 years) and women in island area had higher risk for frailty. Older age and suffering from depression were the independent risk factors for frailty. It is necessary to pay attention to the health risk factors and special environment in island area, and take comprehensive intervention measures to delay the process of debilitation and improve the quality of life of middle-aged and elderly people.

ObjectiveTo analyze the characteristics of death and premature death of 4 major chronic diseases （cardiovascular and cerebrovascular diseases， malignant tumors， chronic respiratory diseases and diabetes） in Taizhou City from 2011 to 2018，and provide data basis for the government to formulate chronic disease prevention planning. MethodsThe death data of household registration residents in Taizhou City from 2011 to 2018 were derived from the Chronic Disease Surveillance Information Management System in Zhejiang Province. The death toll ratio of chronic diseases， the mortality rate of chronic diseases， the probability of premature death of chronic diseases were analyzed. The standardization rate was calculated six times in 2010. Population composition of the census. The Joinpoint Regression Program 4.2 software was used for calculating annual percent change （APC） and its statistical test results. ResultsFrom 2011 to 2018， there were 231 724 chronic disease deaths in Taizhou City， with a mortality rate of 486.52/10⁵ and a standardized mortality rate of 381.55/10⁵. The proportion of chronic disease deaths to total deaths was 79.89%， of which males were higher than females and rural areas were higher than urban areas.From 2011 to 2018， the standardized mortality and early death probability of cardiovascular and cerebrovascular diseases， malignant tumors and chronic respiratory diseases in Taizhou showed a downward trend （P<0.05）， the standardized mortality of diabetes （P=0.46） and the early death probability （P=0.22） did not decline， and the mortality of all age groups of the above four types of chronic diseases in rural areas was higher than that in urban areas. The mortality of the four types of chronic diseases from high to low are cardiovascular and cerebrovascular diseases， malignant tumors， chronic respiratory diseases and diabetes， and the mortality tends to increase with age. From 2011 to 2018， the probability of premature death from four types of chronic diseases in Taizhou City showed a downward trend， from 13.49% in 2011 to 10.49% in 2018， with an average annual decrease of 2.97%. The difference was statistically significant （t=‒5.83，P<0.05）. ConclusionChronic disease death is the main cause of death in Taizhou City. In order to reduce the mortality rate of chronic diseases， effective prevention and control measures for chronic diseases should be carried out， especially the prevention and control of diabetes and male chronic diseases.

Objective:To evaluate the efficacy and side effects of PD-1 monoclonal antibody in the treatment of advanced metastatic renal cell carcinoma in China.Methods:The clinical data of 117 patients with advanced metastatic renal cell carcinoma (mRCC) treated with PD-1 monoclonal antibody from October 2016 to February 2022 were retrospectively analyzed. There were 87 males (74.4%) and 30 females (25.6%), with an average age of (57.9±10.9) years old, BMI of (23.6±3.4) kg/m 2and smoking history of 79 (67.5%). There were 44 cases (37.6%) with hypertension, 19 (16.2%) cases of diabetes. The ECOG score of 59.8% (70/117) patients was 0, 33.3% (39/117) was 1, 4.3% (5/117) was 2, and 2.5% (3/117) was 3. The pathological type of 104 cases were renal clear cell carcinoma (ccRCC), 8 cases of papillary renal cell carcinoma, 2 cases of chromophobe cell carcinoma, 2 cases of collecting duct carcinoma and 1 case of eosinophilic cell carcinoma. The general condition of the overall population and the overall survival (OS) of relevant subgroups were analyzed. Secondary goals included progression free survival (PFS), objective response rate (ORR), adverse reactions, overall survival (OS), and progression free survival (PFS). Results:65.8% (77 / 117) of the patients chose targeted combined with PD-1 monoclonal antibody in the first-line treatment. The main targeted drugs were acitinib (81.8%, 63 / 77), tirelizumab (37.6%, 29 / 77) and cindilimab (25.9%, 20 / 77). After first-line treatment, 19.6.1% (23 / 117) patients needed to be converted to second-line treatment, and 15 patients changed the type of PD-1 antibody during treatment. In addition, the targeted drug of combined therapy was replaced by acitinib in 8 patients. The main causes of drug withdrawal were disease progression (70.7%, 29 / 41) and death (29.2%, 12 / 41). The median OS of the overall population was 35.6 (19-60) months and PFS was 12.1 (1-60) months. The ORR of the overall population was 47.8% (56 / 117). 4.2% (5/117) patients had complete remission, another 17.0% (20/117) patients were in stable condition, and 43.5% (51 / 117) patients were in partial remission. In the first-line treatment, the median PFS time of targeted combined with PD-1 monoclonal antibody was 12.6 (1-30) months, the median PFS time of PD-1 single drug immunotherapy was 10.5 (1-60) months. In the second-line treatment, the PFS of patients treated with PD-1 monoclonal antibody was 10.1 (4-19) months, and that of patients treated with PD-1 monoclonal antibody combined with targeted therapy was 11.7 (1-25) months. The most common adverse reactions were elevated blood pressure (18.5%, 23 / 124), followed by hypothyroidism (15.3%%, 19/124), rash (14.5%, 18 / 124), elevated transaminase (10.5%, 13 / 124) and bone marrow suppression (9.7%, 12/124). 9.4% (11 / 117) patients needed to reduce the related adverse reactions by interrupting the treatment control of PD-1 monoclonal antibody.Conclusions:The safety and efficacy of PD-1 monoclonal antibody in domestic patients are better, and the side effects are less. The efficacy and safety of PD-1 monoclonal antibody combined with targeted therapy in the real world population are consistent with many key clinical trials abroad. PD-1 monoclonal antibody combined with targeted drugs can be popularized in the domestic MRCC population.

There were statistically significant differences in the mortality rates of residents between different age groups （P<0.05）. Except for there were no statistically significance differences between the mortality rates of 15-44 years old and 0-14 years old in 2013 and 2014（both P>0.008 3）. The mortality rate in each year from 2010 to 2016 were decreased by 0-14 years old,15-44 years old,45-64 years old,65 years old and above group （all P<0.008 3）. The mortality rate of all age groups showed a downward trend year by year（P<0.05）. The top five injury death causes were accidental falls（17.97/100 000）,motor vehicle traffic accidents（13.97/100 000）,drowning（5.59/100 000）,suicide （5.25/100 000）,other accidents and harmful effects（4.50/100 000）,accounting for 84.35% of the total number of deaths. The injury death causes of the 0-14 years old group were mainly drowning,which was 407 cases,accounting for 1.55% of the total number of deaths; for 15-44 years old group and the 45-64 years old group,the main causes were motor vehicle traffic accidents,which were 1 373 and 2 354 cases,accounting for 5.22% and 8.95%,respectively; for 65 years old and above group,the main cause was mainly accidental falls,which was 6 777 cases,accounting for 25.76%. The years of potential life lost （PYLL） due to injury was 328 678 person-years and the years of potential life lost rate （PYLLR） was 7.95‰. Conclusion The injury mortality rates of Taizhou residents were declined from 2010 to 2016. The mortality rate of elderly residents due to injury were high and accidental falls was the main cause of injury deaths.
